Patent WO-9717473-A1 (WO)
Title: Procedure duplex de production de metaux et d'alliages de metaux a partir de minerais de metaux oxydiques
Inventor: INNES JOHN ALEXANDER
IPC: F27B15/09
Filed: 1996-11-04
Abstract: Lors de la production d'une matière de base hautement métallisée, consistant en un produit intermédiaire obtenu uniquement à l'aide de réducteurs gazeux lors de processus de réduction en deux étapes de ce type, on se heurte à des problèmes de collage qui entravent le processus de traitement continu et diminuent le rendement. Ce problème a pu être résolu en utilisant un matériau carboné hautement volatile, tel que du charbon, en qualité d'agent de réduction de la matière de départ à base de minerai d'oxyde (partiellement réduit), ceci lors de l'étape de préréduction à l'état solide d'un processus duplex et afin de produire un métal (alliage) final, l'étape finale consistant en la fusion. Les produits intermédiaires de la première étape consistent en un produit de carbonisation du charbon, lequel permet de résoudre le problème de collage, en du minerai et du CO partiellement réduits, et en du H2 qui participent à la préréduction. Ce processus peut tout particulièrement être appliqué à des minerais de fer, tel que de l'hématite, de la magnétite et des dérivés similaires, notamment des minerais de chromite et de nickel oxydique. Ce processus peut également être de type triplex, lequel consiste, en ce cas, à effectuer un séchage, un préchauffage et une réduction partielle lors de la première étape, puis à effectuer une autre réduction partielle, et, enfin, à passer à l'étape de fusion. Les installations destinées à ce processus peuvent comprendre un four à cuve de fusion ou un lit fluidisé afin d'effectuer la séquence de préréduction, de préférence un lit fluidisé. Il est préférable d'utiliser, dans le processus triplex, deux lits fluidisés associés (3, 5). Tout four approprié (7) peut être utilisé dans l'étape de fusion du moment qu'il possède des équipements d'injection de minerai partiellement réduit, de produits de carbonisation et de flux, des dispositifs de type lance à air chaud, des dispositifs pour les effluents gazeux, ainsi que des dispositifs pour la coulée de métal et de scories fondus. L'étape finale de réduction à l'état solide se fait à une température d'au moins 550 °C, de préférence entre 750 et 900 °C. Il est nécessaire d'avoir une métallisation d'au moins 50 % pour obtenir un traitement satisfaisant, et de préférence, une métallisation d'au moins 80 %.

Title: Bridge hydroinsulation
Inventor: DARAKCHIEV BOGOMIL D
IPC: E04D11/02
Filed: 1990-04-24
Abstract: The watertightness is intended to be applied in bridge building and with flat roofs. It has better safety and a longer life span and its production does not depend on weather conditions, as no bitumen materials are used. Besides, it helps transferring the braking forces from the bridge decking to the bridge bearing structure. The watertight consists of a watertight layer (2), over the bridge bearing structure (1), enveloped on both sides with geotextile (3). Small thresholds (6) are formed on the bridge bearing structure (1), transversally to the bridge. The watertight layer (2), enveloped on both sides with the geotextile (3) is laid free on the bearing structure (1) and over the small thresholds (6), with polyethylene foil (7) being laid also free over the layer. Over the foil (7), is a concrete protective layer (4) and over it the road decking (5).

Title: Method for the regeneration of copper-tin activating additive
Inventor: KAROLEVA VIOLETA D
IPC: C22B3/20
Filed: 1993-05-04
Abstract: This method finds application in zinc hydrometallurgy. It enables increasing the rate of regenerating the spent copper-stannous activating additive at relatively low temperatures. The spent activating additive undergoes acidic treatment, whereby cobalt, nickel and tin are dissolved with the copper remaining in metallic copper powder form. This is followed by selective hydrolysis settlement of the tin from the resulting solution and dissolving the stannous hydrolysis precipitate and the metallic copper. The copper-stannous activating additive settles from the solution through cementation.

Title: Moule compact a actionnement coulissant
Inventor: JOSEPH EALIAS C
IPC: B29C45/33
Filed: 2002-02-22
Abstract: L'invention concerne un appareil de moulage qui comprend une paire d'inserts coulissants (30, 32) qui viennent au contact ou se dégagent des autres composants du moule par un mouvement latéral. Ce mouvement latéral des inserts coulissants (30, 32) est du à un mécanisme coulissant qui comprend une crémaillère d'entraînement (46), une paire de pignons d'entraînement (52, 54) à chaque extrémité de la crémaillère d'entraînement (46), deux paires de crémaillères entraînées (60, 62) et une pluralité de glissières (34, 36) reliées aux crémaillères entraînées (60, 62). Les crémaillères entraînées (60,62) de chaque paire, qui sont parallèles et espacées les unes des autres, viennent s'engrener sur les côtés opposés d'un pignon (52, 54) et sont, par conséquent, entraînées dans des directions opposées par rotation du pignon (52, 54). L'appareil de moulage selon l'invention est plus compact que les dispositifs classiques munis d'inserts coulissants. De plus, il rend superflues les pinces de retenue, supprime les obstructions entre les plaques de moules lorsque les plaques sont séparées et peut effectuer des cycles beaucoup plus rapides que les dispositifs classiques.

Title: Apparatus for supplying offset printing presses with a cooled damping solution
Inventor: SARDA JEAN L
IPC: B41F7/32
Filed: 1990-06-13
Abstract: ABSTRACT OF THE DISCLOSURE      An apparatus for supplying offset printing presses with a cooled damping solution uses a damping tray. The damping tray is subdivided into two distinct portions.  A reserve portion contains concentrated solution supplied from a source of damping solution. The distribution solution communicates with a ductor roller.  Restrictive holes formed in the partition dividing the two portions of the tray have a flow rate that is directly related to the amount of damping solution being used by the ductor roller in the printing press.  This flow rate, being very small, allows flow only from the reserve portion into the distribution portion of the tank.

Title: Cone-shaped apparatus for tempering boiled candy
Inventor: VAN DONGEN DAVID B
IPC: A23G3/02
Filed: 1990-06-28
Abstract: ABSTRACT      A candy tempering apparatus for tempering a mass of hard candy material to a desired consistency comprises an inverted, truncated cone having an open top, an open bottom, and an inner surface having an upper rim portion.   The cone is rotatable about its longitudinal axis and a feeder deposits molten candy material onto the upper rim.   Fixedly positioned coaxially in the cone is a stator having adjustable arms carrying plows and rollers for advancing the candy material from the upper rim down the inner surface of the rotating cone and out through the open bottom.  Also included are means for adjusting the speed of  rotation,  and  the  lateral positioning of  the adjustable rollers and plows with respect  to the inner surface of the cone,   for   kneading   the   candy  material  to  a  desired consistency.  The cone may have a variable angle of inclination to accommodate the change in consistency of the candy as it cools,  so that the cone is steeper toward the bottom of the cone.   To help maintain desired  consistency and adjust the degree  of  cooling  to  maintain  a  constant  temperature  for tempering the candy, there is included a temperature probe and sensor  which may be  controllably connected  to a network of fluid spray heads about the outside of the cone, as well as to an air blower positioned over the open top of the cone, for controllably cooling the candy material.
